Yeah it has a rigid body...
Essentially all I'm trying to do is move a cube via the touch screen, only I want the cube to not be able to go through other walls.
Setting the position of the cube to be the position of where the player is touching seems to completely override any collision detection that may be taking place. I've tried using physics to add force towards where the player is touching, but that seems to make the cube go all crazy and shakey when it's trying to go through the wall.
